Researchers identify genetic basis for anti-neutrophil cytoplasmic antibody-associated vasculitis

Autoimmune disease is fundamentally a mystery: whyever should an organism systematically set out to harm itself?

Study sheds light on possible lung damage caused by COVID-19 virus

The study, published today in The Lancet's eBioMedicine, by King's College London in collaboration with University of Trieste and the International Centre for Genetic Engineering and Biology in Italy, shows the unique characteristics to the SARS-CoV-2 virus and may explain why patients suffer from 'long COVID'.

Swelling may be important for protecting the brain after injury, study reveals

Following a brain-injuring bump or blow to the head, brain cells and blood vessels typically swell. This can lead to a potentially life-threatening increase in pressure inside the skull, and managing swelling is critical for patients with traumatic brain injuries (TBIs).

Beta-blockers could be used to treat COVID-19, study finds

Beta-blockers could potentially be used to treat COVID-19, according to a new international study by Italian and Australian scientists.

Blood vessel malformations originate in vein cells

In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers from Uppsala University can now show, at molecular level, that these changes originate in vein cells.

Study estimates the proportion of COVID-19 deaths due to air pollution

Long-term exposure to air pollution generated by human activity is linked to about 27 per cent of COVID-19-related deaths in East Asia and 15 per cent mortality in South Asia and worldwide. These deaths could be largely prevented by adopting air quality regulations, says a new study.

Two studies find age as a primary factor in melanoma treatment resistance

Age may cause identical cancer cells with the same mutations to behave differently. In animal and laboratory models of melanoma cells, age was a primary factor in treatment response.

SARS-CoV-2 virus may target red marrow and prevent the formation of new erythrocytes

Specialists from the Department of Fundamental Medicine of Far Eastern Federal University (FEFU) with Russian and Japanese colleagues have probed into mechanisms of COVID-19 inside-the-body distribution linked to erythrocytes damaging.

SARS-CoV-2 spike proteins can directly impact the blood-brain barrier

Like a key, SARS-CoV-2 - the virus that causes coronavirus disease 2019 (COVID-19) - attaches to specific molecules on the host cell surface, opening gateways into the cell interior.

COVID-19-related myocarditis may be a relatively rare occurrence, indicates study

A study conducted by Richard Vander Heide, MD, PhD, Professor and Director of Pathology Research at LSU Health New Orleans School of Medicine, and Marc Halushka, MD, PhD, Professor of Pathology at Johns Hopkins University School of Medicine, suggests myocarditis caused by COVID-19 may be a relatively rare occurrence.

Novel device can benefit patients with upper limb paralysis

A tiny device the size of a small paperclip has been shown to help patients with upper limb paralysis to text, email and even shop online in the first human trial.

Brain-computer interface enables patients with severe paralysis to resume daily tasks

Researchers demonstrated the success of a fully implantable wireless medical device, the Stentrode™ brain-computer interface (BCI), designed to allow patients with severe paralysis to resume daily tasks -- including texting, emailing, shopping and banking online -- without the need for open brain surgery.

A systematic review and meta-analysis of stroke in COVID-19 patients

Fourteen out of every 1,000 COVID-19 patients admitted to hospital experience a stroke, a rate that is even higher in older patients and those with severe infection and pre-existing vascular conditions, according to a report published this week.

Novel cardiac patch improves recovery from heart attack in rats and pigs

According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years.

Researchers demonstrate potent antibody that fights against coronavirus

Scientists at Fred Hutchinson Cancer Research Center in Seattle have shown that a potent antibody from a COVID-19 survivor interferes with a key feature on the surface of the coronavirus's distinctive spikes and induces critical pieces of those spikes to break off in the process.

Scripps Research scientists uncover potential new strategy for treating eye diseases

Scientists at Scripps Research have uncovered a potential new strategy for treating eye diseases that affect millions of people around the world, often resulting in blindness.

'White matter lesion' mapping tool can detect early signs of cognitive decline

A new tool for analyzing tissue damage seen on MRI brain scans can detect with more than 70 percent accuracy early signs of cognitive decline, new research shows.

About 15% of COVID-19-related deaths linked to long-term exposure to air pollution

Long-term exposure to air pollution has been linked to an increased risk of dying from COVID-19 and, for the first time, a study has estimated the proportion of deaths from the coronavirus that could be attributed to the exacerbating effects of air pollution for every country in the world.

Researchers generate a transcriptomic map of the COVID brain

COVID-19 is known to be associated with multiple changes in gene expression, but many of these are also seen in chronic brain conditions as well as in some abnormal mental conditions. A recent study published on the preprint server bioRxiv in October 2020 uncovers the molecular basis of this association.
